目的 了解社区人群左室肥厚的患病率及其影响因素。方法 对上海市南市区高血压人群进行横断面调查。结果 调查高血压人群 16 86人 ,其中男性 978人 ,女性 70 8人。左室肥厚患病率为 2 9.2 % ,男女性分别为 2 5 .4 %和 34.5 % ,女性明显高于男性 (χ2 =16 .17,P <0 .0 1) ,且患病率在两性均随年龄而增加 ,在 4 5～、5 5～、6 5～岁年龄段男女性别之间左室肥厚的患病率差异均有显著性 (P <0 .0 5 )。单因素及多因素分析结果表明性别、年龄、文化程度、体重指数、收缩压均是左室肥厚的影响因素 ,其中文化程度为保护性因素。结论 社区中老年人左室肥厚的患病率高 ,与多种复杂因素有关 ,应从多方面对这些因素进行针对性防治。
Objective To understand the prevalence of left ventricular hypertrophy in community population and its influencing factors. Methods A cross-sectional survey was conducted on hypertensive people in the southern urban area of Shanghai. Results A total of 16 86 hypertensive patients were investigated, including 978 males and 70 8 females. The prevalence of left ventricular hypertrophy was 29.2%, male and female were 25.4% and 34.5% respectively, females were significantly higher than males (χ2 = 16.17, P < 0.01), and the prevalence rate in both sexes Both increased with age, and the prevalence of left ventricular hypertrophy was significantly different between males and females in the 45-, 55-, and 65-year-old age groups (P < 0.05). Univariate and multivariate analysis showed that gender, age, education level, body mass index, and systolic blood pressure were the influencing factors of left ventricular hypertrophy, and the education level was a protective factor. Conclusion The prevalence of left ventricular hypertrophy is high in middle-aged and elderly people in the community and is related to a variety of complex factors. These factors should be targeted and controlled in many aspects.
